12V Switching Car PSU by UC3843

Monday, November 26th, 2007

The power supply accepts 8 to 16 volts and produces 12 volts. The topology is SEPIC (single-ended primary inductance converter), the advantage being the ability to convert up or down with a minimum of parts and maximum efficiency. [...] the power supply is good for about 8 amps output and can power the system while [...]

Switching Power Supply by IC UC3843 + IRF740

Tuesday, June 26th, 2007

This is a Somewhat Experimental Circuit and I Especially designed this circuit for those persons that want to Dabble in Switching Power Supply Designs. This Circuit is based on a UC3843 Integrated Circuit. It does Not allow for Feedback control of the output voltage. The output voltage is totally determined by the “Turns Ratio in [...]
